Search for Darkonium in $e^+e^-$ Collisions / BABAR Collaboration
Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. [...]

First Measurement of the Muon Neutrino Charged Current Single Pion Production Cross Section on Water with the T2K Near Detector / T2K Collaboration
The T2K off-axis near detector, ND280, is used to make the first differential cross section measurements of muon neutrino charged current single positive pion production on a water target at energies ${\sim}0.8$ GeV. The differential measurements are presented as a function of muon and pion kinematics, in the restricted phase-space defined by $p_{\pi^+}>200$MeV/c, $p_{\mu^-}>200$MeV/c, $\cos \theta_{\pi^+}>0.3$ and $\cos \theta_{\mu^-}>0.3$. [...]

Measurement of coherent $\pi^{+}$ production in low energy neutrino-Carbon scattering / T2K Collaboration
We report the first measurement of the flux-averaged cross section for charged current coherent $\pi^{+}$ production on carbon for neutrino energies less than 1.5 GeV to a restricted final state phase space region in the T2K near detector, ND280. Comparisons are made with predictions from the Rein-Sehgal coherent production model and the model by Alvarez-Ruso {\it et al.}, the latter representing the first implementation of an instance of the new class of microscopic coherent models in a neutrino interaction Monte Carlo event generator.

The mass-hierarchy and CP-violation discovery reach of the LBNO long-baseline neutrino experiment / LAGUNA-LBNO Collaboration
The next generation neutrino observatory proposed by the LBNO collaboration will address fundamental questions in particle and astroparticle physics. The experiment consists of a far detector, in its first stage a 20 kt LAr double phase TPC and a magnetised iron calorimeter, situated at 2300 km from CERN and a near detector based on a high-pressure argon gas TPC.

The Electromagnetic Calorimeter for the T2K Near Detector ND280 / T2K UK Collaboration
The T2K experiment studies oscillations of an off-axis muon neutrino beam between the J-PARC accelerator complex and the Super-Kamiokande detector. Special emphasis is placed on measuring the mixing angle theta_13 by observing electron neutrino appearance via the sub-dominant muon neutrino to electron neutrino oscillation, and searching for CP violation in the lepton sector.

T2K neutrino flux prediction / T2K Collaboration
The Tokai-to-Kamioka (T2K) experiment studies neutrino oscillations using an off-axis muon neutrino beam with a peak energy of about 0.6 GeV that originates at the J-PARC accelerator facility. Interactions of the neutrinos are observed at near detectors placed at 280 m from the production target and at the far detector -- Super-Kamiokande (SK) -- located 295 km away. [...]

Measurement of the branching ratio of the decay $\Xi^{0} \rightarrow \Sigma^{+} \mu^{-} \overline{\nu}_{\mu}$ / NA48/1 Collaboration
From the 2002 data taking with a neutral kaon beam extracted from the CERN-SPS, the NA48/1 experiment observed 97 $\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$ candidates with a background contamination of $30.8 \pm 4.2$ events. From this sample, the BR($\Xi^{0}\rightarrow \Sigma^{+} \mu^{-} \bar{\nu}_{\mu}$) is measured to be $(2.17 \pm 0.32_{\mathrm{stat}}\pm 0.17_{\mathrm{syst}})\times10^{-6}$..

New precise measurements of the $\Xi^{0} \to \Lambda \gamma$ and $\Xi^{0} \to \Sigma^{0}\gamma$ decay asymmetries / NA48/1 Collaboration
The decay asymmetries of the weak radiative Hyperon decays $\Xi^{0}\to \Lambda \gamma$ and $\Xi^{0} \to \Sigma^{0}\gamma$ have been measured with high precision using data of the NA48/1 experiment at CERN. From about 52000 $\Xi^{0}\to \Lambda \gamma$ and 15000 $\Xi^{0} \to \Sigma^{0}\gamma$ decays, we obtain for the decay asymmetries $\alpha_{\Xi^{0}\to \Lambda\gamma}$ = -0.704 +- 0.019$_{stat}$ +- 0.064$_{syst}$ and $\alpha_{\Xi^{0}\to \Sigma^{0}\gamma}$ = -0.729 +- 0.030$_{stat}$ +- 0.076$_{syst}$, respectively.
